Thesp joins Perry, Campbell in WB pic

NEW YORK — Oliver Platt will become the third member of the trio in Warner Bros.’ “Three to Tango,” which stars Matthew Perry and Neve Campbell.

Helmed by Damon Santostefano, pic will begin lensing April 29 in Toronto.

Platt will play a two-timing ad man who asks his employee, played by Perry, to act as an escort for his mistress, portrayed by Campbell. Platt doesn’t consider Perry a romantic threat because he assumes Perry is gay. But Platt is wrong and Perry ends up falling for Campbell.

“Tango” is being produced by Robert Newmyer and Jeffrey Silver.

Platt is currently onscreen in Warner Bros.’ “Dangerous Beauty.” Next month, he will be seen opposite Warren Beatty and Halle Berry in Beatty’s political drama “Bulworth.”

In May, Platt will travel to Cannes for the premiere of Fox Searchlight’s “The Imposters,” which will screen in Un Certain Regard.

Later in the summer, Platt will appear on the bigscreen with Eddie Murphy in the remake of “Dr. Dolittle.”

He is represented by Frank Frattaroli and Michelle Stern at William Morris, Irwin Stoff at 3 Arts Management and attorney Barry Hirsch.
